I would see if MI' could recommend something that he could make as a total replacement. As far as I am aware, there is nothing special about the terminations. When I find a final resting place for my Prime I'll probably do the same.

My cable is much longer than 1.2m and is a little too ridged/weighty for my liking so over time it just starts to drop and/or drag on things.
